Hi--I have Rh neg blood type-- have had 3 Rh positive pregnancies. Each time I have had a baby ---I have had to decide whether to take the Rhogam shot. I am aware that it is made from blood fractions,the gamma globulins (separated from the plasma by serum protein electolysis). Years ago, I had called the War Memorial Blood Bank, in our local area, asking how Rhogam was produced. From the reply I received-- now,over 20 years ago---my understanding was Rhogam is produced from the donated blood of many Rh neg women, whom had developed antibodies from their Rh positive babies. This was from post World War II women(?)---and the blood was collected and pooled---then the fractions were spun off from the blood to form the passive immunization.
Does anyone know if this is accurate information on how Rhogam is made today?
